This will most likely end up causing an ABI breakage so I think the best option is the least complicated time format, that is what parse_timestamp() provides. In case arbitrary format really must be supported then I think the best option is to parse_timestamp() and if that fails call getdate() as well. That said I have no idea how to write instructions to manual page about DATEMSK environment variable and strptime() formats without causing new-to-linux users to wonder why simple things must be so hard. -- Sami Kerola http://www.iki.fi/kerolasa/
